    Opposing JAK-STAT and Wnt signaling gradients define a stem cell domain by regulating differentiation at two borders

    David Melamed, Daniel Kalderon
    Graded Wnt and JAK-STAT signals regulate the division rate, AP location and differentiation of Drosophila ovarian follicle stem cells to define a domain of stem cells maintained by population asymmetry.

    Epigenetic reprogramming rewires transcription during the alternation of generations in Arabidopsis

    Michael Borg et al.
    Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.

    Human genetic analyses of organelles highlight the nucleus in age-related trait heritability

    Rahul Gupta et al.
    Although cellular organelles show a functional deterioration in aging, genetic loci associated with common age-associated disease instead nominate nuclear transcription factors across several age-related diseases.

    Human cytomegalovirus IE1 protein alters the higher-order chromatin structure by targeting the acidic patch of the nucleosome

    Qianglin Fang et al.
    Distinct binding of viral proteins to the same region on the nucleosome surface can result in contrasting changes to higher-order chromatin structure in the host cell.

    Hsp70-associated chaperones have a critical role in buffering protein production costs

    Zoltán Farkas et al.
    Protein biosynthesis and protein quality control jointly determine protein production costs.

    Synthetic and genomic regulatory elements reveal aspects of cis-regulatory grammar in mouse embryonic stem cells

    Dana M King et al.
    The independent effects of transcription factor binding sites are large regardless of sequence context, but the interactions between sites are context dependent.

    Tumor copy number alteration burden is a pan-cancer prognostic factor associated with recurrence and death

    Haley Hieronymus et al.
    The percentage of a tumor’s genome with alterations in copy number is correlated with increased mortality across a range of tumor types and can be measured using a clinically approved sequencing assay.

    Reconceiving the hippocampal map as a topological template

    Yuri Dabaghian et al.
    Empirical evidence suggests that the hippocampus constructs maps of spatial environments based on the relative locations of places (i.e., topology), rather than absolute distances and coordinates (i.e., geometry).

    Bimodal function of chromatin remodeler Hmga1 in neural crest induction and Wnt-dependent emigration

    Shashank Gandhi et al.
    Chromatin remodeler Hmga1 has two separable functions in neural crest development, first neural crest specification at the neural plate border and later in Wnt-dependent emigration from the neural tube.

    HIV-1 integrase tetramers are the antiviral target of pyridine-based allosteric integrase inhibitors

    Pratibha C Koneru et al.
    Pyridine-based allosteric inhibitors selectively target HIV-1 integrase tetramers and exhibit enhanced antiviral activity against a dolutegravir resistant mutant virus indicating potential clinical benefits for combining these two classes of inhibitors.
